ATTACHMENT CORD.

Application led May 8, 1926. Serial No. 107,800.

i My invention relates to terminal connectors for flexible conductors, more par# ticularly, to attachment cords for domestic appliances.

It is among the objects of my invent-lon to provide a terminal connector for appliances which comprises a minimum number of c0- operating parts of insulating material having conductor elements and connecting terminals embedded therein and which shall be adapted for universal movement as and for the purpose as will be hereinafter set forth.

ln the general use ot domestic appliances., particularlysad irons it has been common experience to break or rupture the flexible conductor cord attached to the terminal by the manipulation oit the .appliance resulting in the short-circuiting of the conductor'terminals and frequently in the blowing out of line fuses.

Various forms of terminal conductors have been heretofore proposed to obviate these ditlicultiesand most of these prior types provided for relative movement of the portion of the connector to which the cord 4is attached with the terminal vportion attached to the appliance, such movements being` provided in a given plane.

lt is the purpose ot' my present invention to provide a terminal connector which is designed to permit universal movement ot the cord connecting element relative to the terminal connector.

In the accompanying drawing constituting a part hereotl and in which like reference characters designate like parts, Fig. 1 is a side elevational view of an electric sad iron .having a universally movable terminal connector embodying the principles ot` my invention attached thereto ;y Fig. 2 is a longitildinal sectional View through the terminal connector illustrating the manner in which the several parts are associated and further illustrating the several connections of the conductor elements embodied in these parts; Fig. 3 is a cross-sectional vien7 taken on the lines lll-HI, Fig. 2; Fig. 4 is a view partially in section and partially in elevation ot the terminal member taken on the lines lil-IV, Fig. 2; Fig. 5 is a longitudinal scct-ional view of a modified form of tern'iinal connectors; and Figs. G and 7 are cross-sectional views of the cooperating terminal connector members.

Referring to the several gures of the drawing the structure embodyingthe elements of my invention comprises a terminal connector generally designated by the reference numeral 1, having a body portion of insulating material such as wood, rubber, or

any of the well known molding compositionsl suitable to be formed into the shapes illustrated. -The member l comprises parts 2 and 3 provided with countersunk openings 4 adapted to receive screws 5 for joining them.

rllhe member 3 is provided with a cut-away portion 6 to provide a space for mounting a movable insulator 7, the latter being preterably of yoke shape for receiving'a terminal bushing 8 in which the ends of a flexible cord or current-carrying conductor 9 are secured as by screws 10, Fig. 2.

Referring to Fig. 4 et the drawing the member Sis provided with a pair of spring contacts 11 and 12 having their surfaces 13 shaped complementary to the terminals 14 of the sad iron shown in dotted lines in Fig. l. Conductors 15 and 16 extendingthrough openings 17 and 18 are respectively secured to the contacts 11 and 12 by screws 19. The conductors 17 and 18 are secured to terminals 20 and 21, Fig. 2 having apertures 22 provided 'therein for receiving a pair or' trunnion-shaped terminals 23 of the yoke member 7. llhe terminals 23 are connected by conductors 24, Fig. 3 to apertured vterminals 25 and 26 of the yoke, which in The modified form of terminal connectorsshown in Figs. 5, 6 and 7 comprise the parts 2 and 3 of Figs. 1 and 2 having conductors 15 and 16 and terminal posts 21 and 22. lnstead of the sleeve 8 for securing 'the flexible cord 9, the latter is connected directly to a yoke having conductors 31 secured to terminals 32 and 33, they being adjustable for assembly purposes. An insulating block 34 having conductors 35 and 36 projecting in the manner shown to constitute trunnions for llt) " vides a simple mechanical and electrically efficientconnecting means for attaching the flexible conductor to electrical appliances and thatv the several parts in cooperative relation provideuniversal movement whereby the cooperating elements and particularly the conductor connections are relieved of detrimental stresses and twisting as was the fre-l quent cause of annoyance in prior art devices.

Although I have described the specific embodiment of my invention it will be obvious to those skilled in the art that various modifications may be made in the details of construction and in the shape and arrangement of the several cooperating parts Without departing from the principles herein set forth.

I claim:

1. A terminal connector for flexible conduct/ors comprising in combination a connector member provided with contacts for the terminals to which it is to be joined, a yoke of insulating'material pivotally mounted thereon, and another terminal member pivotally connected to said yoke.

2. A terminal connector for flexible conductors comprisingin combination a connector member provided With contacts for the terminals to which it is to be joined, a movable insulator pivotally connected thereto, and a terminal bushing pivotally connected to said insulator.

3. A terminal connector for flexible con- 4ductors comprising in combination a connector member provided with contacts for Leidse@ theterminals to which it is to be joined, a movable insulator pivotally connected thereto, and a terminal bushing pivotally connected to said insulator, said connector, movable insulator and terminal bushing being adapted for universal movement.

4. A terminal connector for flexible conductors comprising in combination a connector member provided with contacts for the terminals to which it is to be joined, a movable insulator pivotally. connected thereto, and a terminalbushing pivotally connected to said insulator, and relatively movable terminal connections for said connector, insulator and bushing to provi-de a currentcarrying circuit and to permit universal movement of said parts.

5. A terminal connector for rflexible conductors comprising in combination a connector member provided with contacts for the terminals to which it is to be joined, a movable insulator provided With trunnions adapted for'engagement with said member and having conductors embedded therein, and a terminal bushing for securing the respective ends of a flexible two-ply conductor, said bushing having extending terminals for engaging the embedded conductor of said movable insulator. i

6. A terminal connector for flexible conductors comprising in combination a connector member provided with contacts for the terminals to which it is to be joined, a movable insulator provided with trunnions adapted for engagement with said member and having conductors embedded therein, and a terminal bushing for securing the respective ends of a flexible two-ply conductor, said bushing having extending terminals for engaging the embedded conductor of saidmovable insulator and said connector, insulator and bushing beingr adapted for universal movement without interrupting their respective connections.

'ln testimony whereof, I sign my name.
